Abstract

Background: palladium allergy has increased considerably in the last few years. Whilst much is known about nickel allergy, the role of palladium as a potential allergen is still unclear. Materials and methods: during a 9-month period we patch tested 63 patients affected by contact dermatitis who had been subdivided in 2 groups: group A, comprising 20 patients with dental or orthopedic prostheses, and group B, comprising 43 patients with present or anamnestic contact dermatitis to metals. Results: in the first group 7 patients (35%) had a positive allergic reaction to palladium chloride; 6 of these patients were also allergic to nickel. In the second group 35 patients (81.4%) were positive to nickel; 26 of these (74.3%) were also allergic to palladium. In addition, 4 patients (9.3%) reacted only to palladium. Conclusions: the increased sensitization to palladium and its association with nickel allergy has to be explained and a number of suggestions have been advanced; the increase of palladium sensitizations would seem real, clinically important and likely that sensitization would also have a lower threshold.
